Osmosis
词性分析
名词:指液体通过半透膜的自然渗透过程,通常用于描述水分子的运动。
形容词:在某些专业领域中,可以用来描述与渗透或相似过程相关的事物,但此用法较少见。
词语辨析
与“diffusion”相比,“osmosis”更强调通过半透膜的水分子运动,而“diffusion”则是指分子在空间中的均匀分布。
词汇扩充
Osmotic pressure(渗透压):指通过渗透过程产生的压力。
Osmoregulation(渗透调节):生物体维持内部环境稳定的过程。
近义词
Diffusion(扩散):物质从高浓度向低浓度移动的过程。
反义词
Concentration(浓缩):物质在某个体积内的量增加,通常与稀释相对。
柯林斯词典定义
Osmosis is the process by which water or other solvents pass through a semipermeable membrane from a solution of lower concentration to one of higher concentration.
牛津词典定义
Osmosis is the movement of water molecules through a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration.
